The `handle comprises a tubular member 1` at one' end of ber 8 having passageways 9 which is locateda.housing 2 containing' the inlet valvesS and 4 of the device, "and at the other end alhousiiig 5 within which check 'valves 6 va`nd'7 rare located. Arranged adjacent to the valve housing 5 'and'secured th'ei'feto, preferably being welded, isa niemtherein. The member S isprovided with a ieducedfportion 11 havinginternal `and ex- 'ternalscrew threads, and'said reduced portion 11 is provided with an 'annular depres- -13 designates Van `inner member arranged centrally within the device, said member comprising a rearmost portion la'having a lpassageway 15 and a stem portionl which extends forwardly in` tlie'device. Q17 `designates a depressed seat vwhich is formed in the member 8, said depressed Seat 17 being 'adapted to receive tlie'rearmostend' of lthe linner member 13 as'shown 1S designates an annularshoulder wliichis clearly in Fig. V.

formed on the inner member 13. Arranged tosurround a portion ot' the inner member 13 is a sleeve 19, the rearmost face of said sleeve being in contact with f the annular shoulder 18 on the member 18, and said sleeve extends forwardly in the devicefrom said vannular shoulder 18, as shown `in Fig. V. By referring to Fig. V it will be seen that the iearinost portion 14v of lthe inner mem'b'erl is ofgreater diametertlian the stem portion 16 of said inner 'niembeig and f 'as 'the inner diameter of the sleeve19`is approximately the same as the outer diameter Voi' the portion 14 of said member 13, there will be an annular space 20 between aI portioiiof the stein -16 andthe inner face of the forwardfportion of the sleeve 19. 21' designates aplurality of passageivays whcli connect the passageway 15 in theportion 14 ofk the member 13 with the annular space 2O jiist` mentioned. vLocated at the rearmost Yend of the sleeve 19 isi an annular collar portion 22, which is provided With'external screw threads, and an annular flange portion 23 of greater diameterthan the threadedport-ion of said collarportion.

lVhen it isdesired to assemble the parts or' the device which have been described, the

inner member 13 is arranged inplace with its rearinost end in the' depressed seat 17. The sleeve 19 is then passed over the inner member 13 and is moved rearwardly until Vthe screw threads on thecollar portion enand 10 formed gage the internal screw threads within the reduced portion 11 or" the member 8. The sleeve 19 is then screwed into the portion 11 until the rearmost'tace oit said sleeve contacts with the shouldery 18. This will cause the rearmost end of the member 1S to be i'orced tightly into the depressed seat 17, whereby a {luid-tight joint will be obtained between the member S and the member 13.'

Then the parts mentioned are assembled as described, the annular face oit the flange portion 23 ot the collar 22 will contact with the tace of the annular depression 12.

24 designates the shell ot the mixing chamber ofthe device, said shell having an annular flange 25 at one ot its ends and a threaded portion 26 at its other end. 27 designates a coupling member which is adapted to connect the shell 2a of the mixing chamber to the member 8, said coupling member being provided with internal screw threads, which engage the external screw threads on the reduced portion 11 ot said member 8, and an annular shoulder 28 which engages a tace ot the annular flange 25 on the shell 2l. It is apparent trom this that when the coupling ymember 27 is screwed on the reduced portion 11 of the member 8 the annular flange 25 of the shell 24k will be tightly gripped between the end tace ot said reduced portion 11 and the annular shoulder 2S'within the coupling member 27. 29 designates a coupling member which is similar to the coupling member 27 just described, said coupling member 29 being adapted to connect the head B of the device to the shell 24.

By referring to Figs. l, IV and Vl it will be noted that there is an annular space SO between the outer tace ot the sleeve 19 and the inner face ot the wall ot the shell 24 of the mixing chamber. lt will also be noted that this space 30 is tapering, due to the fact that the inner face of the wall ot the shell 24 is inclined. Formed in the collar portion 22 of the sleeve 19 is a plurality ot openings 31, said openings being extended entirely through said collar portion, as shown in Fig. V. rlhe sleeve 19 is provided with a non-circular portion 32, said portion 32 having a plurality7 ot dat Jfaces as shown clearly in Fig. Vl. 1t will be noted that when the non-circular portion ot' the sleeve 19 is introduced into the rearmost portion of the circular opening in the shell 2li. spaces 33 will be provided between the flat 'faces of said non-circular portion and the curved tace ot the opening, and these spaces 33 are in registration with the openings 31 Vl). It is therefore plain that fluid which passes from the passageway 10 in the member 8 will pass through the openings 31 and through the spaces 33 into the tapering space 30. It is likewise plain that fluid which passes through the passageway 9 will pass through the pasageway 15 and through the passageways 21 into the space 20.

Arranged in the housing 2 is a pair of passageways Se and 35 through which oxygen and acetylene pass trom reservoirs, said passageways having the inlet valves 3 and l associated with them so that the flow ci oxygen and acetylene trom said passageways into the passageways 35 and 36 may be regulated. 37 designates a tube by which the passage 34- is placed in communication with the valve chamber within which the check valve 6 is located, and 38 designates a tube by which the passageway 35 is placed in communicati on with the valve chamber within which the check valve 7 is located. lt will be noted that the valves 3 an d l are arranged approximately at right angles to each other,

and it will also be noted that comparatively v large spaces 3 and 4 are provided adjacent to the valve seats so that a sufficient space is provided for the unrestricted passage ot iiuid when the valve heads ot the valves 3 and il are withdrawn from their seats.

An important advantage ot our improved torch, or blowpipe, over those used hereto tore resides in the unique manner in which the tube 1, which constitutes the handle ot the device, is retained in place. By refers ring to Fig. Il it will be noted that the tube 1 is provided with a key 40 which extends Jrom end to end of said tube. It will be noted trom Fig. l that the housing 2 containing the inlet valves at the rear end of the handle of the device and the check valve housing 5 at the forward end ot' said handle are each provided with a notch e0 which is adapted to receive said key et). The notch in the check valve housing 5 extends from the rearmost tace ot said housing to the point indicated by the reference character X, and said checlr valve housing is provided with external screw threads 41 adjacent tc the point X. To arrange the tube 1 in place on the device, the head B is disconnected from the shell 2l by unscrewing the coupling member 2G. The tube 1 may then be passed over the shell 2l and member S, said tube beine' so positioned that the key 40 thereof will pass through the notch in the check valve housing 5. A continued longitudinal movement of the tube 1 will cause the rearmost end portion of the notch in the inlet valve housing 2, and it is plain that with the key l0 located in the notches as described, the tube 1 may not be rotated relative to the device. To prevent the tube 1 from being moved forwardly after it has been arranged in place as described, I lemploy an internally threaded ring 4-.2 which is screwed on the member 5, the threads of said ring engaging the screw threads Ll1 on said member 5 and said lring key 40 to enter the Another iin'pogrtant'feature ofV our invention resides 'in the `con'struction which permits .of the easy 1introduction and rcmoval of,thecheickr vali/est and 7. It will,`

be -holed that the "check valve housing 5 and the men'iberSare cutaway as shown clearly in Fig. II toprovide pockets which are in alinement with the chambers within which said check valves are located. The pockets mentioned permit the valves 6 and 7 to kbe moved longitudinally relative to that portion of the device whereby said valves may be moved freely when they are being inserted or removed without interference from any portion of the device. Itis apparent that if the parts mentioned were not so arranged the check valve housing would have to be'much larger in diameter than the adjacent parts of the device to permit longitudinal movement of the check valves.

In the use of our improved device, oxygen passes from the reservoir through the tube 37 and through the valve chamber which contains the check valve 6. The oxygen then passes through the passageway 9 and passageways y2l intothe annular space 20.

At the same time theV acetylene passes from Y,

the reservoir through the tube 38 and through the valve chamber which contains the check valve 7. Y through the passageways 8l and spaces into the space 30. It is therefore apparent that there is a tubular body of oxygen surrounding a tubular body of acetylene, and as these bodies of oxygen and acetylene are discharged from the spaces 2O and 30 they will coininiiigle with each other, thereby producing a complete mixture of ingredients. It is important to notice in connection with the parts just described that the individual passageways 2l are a sufficient distance from the forward end of the space 20 Ato permit the oxygen passing through said passageways 2l to be converted from individual streams of Huid to a single tubular body of fluid having a very thin wall. Also, the individual passagewaysl are located a sufficient distance from the forward end of the space 30 to permit the acetylene to be converted from individual streams of fluid to a tubular body of fluid having a very thin wall. It is therefore plain thatwhen these vtwo tubular bodies of fluid are brought together after leaving the spaces `2() and 30, the thin walls of fluid may be very thoroughly cominingled, thus producing a complete mixture of said fluids.

42 designates a clip which is secured to the tubes 37 and 38 adjacent to the points where said tubes are bent, said clip to preventelongation of said tubes.

It will be seen by referring to Fig. V that the annular space 16 between the stem passes into and through Theacetylene then passes being intended liand :the insideffa'ce of the 'iva-ll ofthe Vshell 2 4 is also tapering, thus compelling the 'gases to pass through 'a very narrow annusaid gases is obtained.
